What is it?Developed to be driven with the roof-down, the Boxster Spyder has a low-slung, lightweight soft-top, with extra-low side windows and two bulges on the single-piece rear lid. Porsche says the car's stretched silhouette is reminiscent of the Carrera GT's.

The Spyder weighs just 1275kg, making it the lightest model in the Boxster range, and 80kg lighter than the Boxster S. Combined with a lower centre of gravity and revised suspension, the car promises scintillating dynamics to reflect its unique look.

PerformanceThe 3.4-litre engine, positioned ahead of the rear axle, develops 320bhp, which is 10bhp more than in the Boxster S.

With the optional PDK semi-auto gearbox and Sports Chrono Package, the new Spyder can blast from 0-62mph in 4.8 seconds. Top speed is 166mph, and average fuel consumption is 30.4mpg.

Around 60% of Boxster buyers add the 1920 PDK gearbox, and Porsche reckons it'll be even more popular on the Spyder.

The Sports Chrono Package includes launch control and promises an 'uncompromisingly' sporty drive.

Historic drivePorsche says that the Boxster family is the successor to the legendary 550 Spyder (click here to see the 550 and Boxster Spyder) built in 1953. Both models are mid-engined, offering low weight and agility for authentic roadster dynamics.

In 2004 and 2008, Porsche produced limited-edition Boxsters with the Spyder badge, but this new car is a specially developed and upgraded production model.
